Calculate the molecular masses of H2,O2,Cl2,Co2,CH4,C2H6,C2H4,NH3,CH3OH.
Answers
Explanation:
Molecular mass of H2 = 2 X atomic mass of H = 2 X 1u = 2u
Molecular mass of O2 = 2 Xatomic mass of O = 2 X 16u = 32u
Molecular mass of Cl2 = 2 X atomic mass of Cl = 2 X 35.5u = 71u
Molecular mass of CO2 = atomic mass of C + 2 X atomic mass of O
= 12+ (2+16) = (12 + 32)u = 44u
Molecular mass of CH4 = atomic mass of C+ 4 X atomic mass of H
= 12+ (4X1)u = (12 + 4)u = 16u
Molecular mass of C2H6 = 2 X atomic mass of C + 6 X atomic mass of H
= (2 X 12 + 6 X 1)u = (24 + 6)u = 30u
Molecular mass of C2H4 = 2 X atomic mass of C+ 4 X atomic mass of H
= (2 X 12 + 4 X 1)u = (24 + 4)u = 28u
Molecular mass of NH3 = atomic mass of N + 3 X atomic mass of H
= (14 + 3 X 1)u = (14 + 3)u = 17u
Molecular mass of CH3OH = atomic mass of C + 3 x atomic mass of H + atomic mass of O
+ atomic mass of H
= (12 + 3 X 1 + 16 + 1)u = (12 + 3 + 17)u = 32u
hope it works
